CAN-REVERSING MECHANISM.

Application led December 24, 1918, Serial No. 268,121. Renewed November 22, 1922.

TaaZZ whom t may 'concern Be it known that I, CHARLES F. MoEwAN, a citizen of the United States, and a resident of the city of Oak Park, county of Cook, and State of Illinois, have invented certain new and useful Improvements in versing Mechanism., of which the following is a specication.v A v My invention relates to improvements in can reversing mechanism designed for use 'especially in connection with can washing machines, "and has for its object the production of. mechanism of this character which will be of' durable 4and economical construction and' highly efficient in use.

A further Objectis the production of can reversing mechanism as mentioned, which will be adapted for'use in connection with cansof various sizes. A still further object .is the productionin lcan washing machinery of an improved arrangement for accommodating cans having covers permanently as,

sociated therewith.

Other objects will appear hereinafter. The invention consists-in the combinations and arrangements of parts hereinafter described and claimed. The invention. will be best understood by reference to the accompanying drawings forming a part of this specilication, and in which,

Fig. 1, is a side elevation of a can washportion of the housing thereof being broken away to expose Aunderlying parts,

Fig. 2, a partially sectional top plan view of the discharge end of the machine,

Fig. 3, an enlarged section taken on substantially line 3--3 of Fig. 1, n Fig 4, a side elevation of the discharge end of thecan washing machine proper, the can discharge passage or Ychute being omitted,

Fig. 5,' av view similar to Fig. 3, showing the method'iof toppling -the can, and

Figs. 6'and 7 enlarged sections taken on 'lines 6-6' and 7-7, respectively, of Fig. 1.

The preferred forni of construction, as illustrated in the drawings, comprises an elongated framework 10, in which is ar.- ranged a can guide which is constituted by spaced parallel bars 11-,11, as'clearly seen in Figs. 2, 6 and 7 Arranged adjacent to and parallel with the can guide Can-Re- :the-passage of the can and cover through the machme during the washing or cleansingoperation, an elongated open space 13 1s rovided intermediate the can and Cover guides, as clearly seen in Figs. 3 and 6.

The feeding or advance i of the can through the machine is lbeing operatively connected with a manuallyopera-ble'lever 16 fulcrumed at 17 at the entrance endv of the machine. The arrangement is such that, through tilting of lever 16, the pawls 14 will be 'reciprocated,A

n n t accomplished through the medium of a plurality of spaced causing intermittent advance of a can -mounted upon the canlguide. In this advance of the can, its cover will of course be correspondingly moved, -inasmuch as. the same is permanently associated therewithv through the medium of the'connecting link 4 C. 'Ihe cleaning or washing of the can and lcover takes place during this intermittent travel, as will be readily understood by those skilled in the4 art.

In order to hold thecovers down in operative relation with the coverguide during the advance of the same .through the machine, an elongated resilient plate or strap' 18 is provided, which is adapted to bear against the tops of the covers, as clearly seen in Figs. 1 and 6. A bar 19 is provided along the side of the cover guide adjacent the can guide,'aga inst which'the covers are adapted to abut, said bar serving to hold the same against lateral displacement from the cover guide, as might otherwise result in the advanceofrthe canto which the cover is attached. i' f Arranged at the discharge end of the can guide is a horizontally positioned platform 20, secured to a supporting bar 21, which is rockingly mounted in ybearings 22 and 23,

-'platform extension 24.

The bar 2l is formed with a laterally promail jecting arm or crank 25, which engages against a strap 26, carried by a reciprocatory bar 27 having operative connection with the operating lever' 16. The arrangement is such that, when the bar 27 is at its rearward terminal of movement, the arm 25 will engage with the straight elevated pore tion of the strap 26, as seen in Fig. 3, and thereby serve to hold the platform 20 in horizontal position, or in the position seen in lFig. 3. Upon foiwvard movement of the bar 27, the arm 25 will be'brought into registration Witlra recess 28 formed in the strap 26, which recess Will permit of the down- .Ward swinging of said arm and hence of corresponding tilting' of the platform to the position seen in .Figa 5. This tilting of the platform is suflicient to effect the toppling of a milk canv Which may be positioned thereon, so that the can will fall laterally toward the left, as seen in Fig. 5.

Provided to the left of said platform is a stationary transversely curved bumper or stop 29, against which the can, when toppled, is adapted to fall, after which the can, by gravity, is caused to completely reverse so as to alight on an adjacently positioned platform 8O in an upright position, as seen in dotted lines in Fig. 5. A rail 31 provided around the platform 30, prevents the can from sliding or being thrown beyond said platform, said rail positively insuring the centering of a can on said platform after topplingofthe same, through the medium of the platform 20.

Leading from the platform 30.i`s an inclined discharge chute 32 down Which the can is adapted to be thrust by a pivoted arm 33, which is fulcrumed at 34C, one end there of engaging with a slot provided in the reciprocatory bar 27.

ldlith the construction set forth it will be seen that in the operation of the machine, the cans will bei*intermittently advanced through the machine through actuations of lever 1G. As each can, with its cover, has passed through the cleansing operatiomthe ysame will be' fed to positionon the platform 20, the cover assuming a position upon the platform extension 24e. rifter.- the can has reached thisposition, upon the nextfor- Ward movement of the bar27, bringing the recess 28 of strap 26 into registration With A the arm 25, platform 20 will be released for? assunse tilting. Said` platform lis unevenly balgagement with the stop 29, whence the same,

by gravity, will be caused to 'completely reverse, finally alighting on the platform 30 in fully righted position, after which the same )will be automatically pushed down the discharge chute by the arm 33..A ln the toppling of the can, the cover thereof, 4of course, is carried along With the same, and by reason of the direction of toppling of the canrelative to the position-'of the connecting link between the can and the cover, the latterl'will be automatically carried to closed position over the tot.1 of 'the can, as seen in F ig. 5. Upon rearward movement of the bar 27, the arm 25 will` again be brought into engagement with the elevated portion of thestrap 26, causing said arm to be rocked upwardly, and hence the platform 2O to be returned to horizontal position in order to accommodate the succeeding can.

lWhile l have illustrated and described the preferred form of construction for. carrying my invention into effect, is capable of variation'and modification without depart ing from the spirit of the invention. therefore, do not Wish to be limited to the precise details of construction set forth, but r desire to avail myself ofsuch variations and modifications as come Within the scope of the appended claims.
